Sathya1, Dr. Share with us what you're looking for, including all the various specs you require, and PCA will deliver custom prototype samples for your evaluation. conduction mode (CRM) integrated buck-flyback power factor correction (PFC) converter with high power factor (PF) and low total harmonic distortion (THD) is proposed in this paper. Simulation and Hardware Prototype of the E-Bike Project. This is a summary of some of. A basic flyback converter requires a switch, which can be a FET or transistor, a Transformer, an output Diode, a Capacitor.
